1. Arrange students into groups. Each group needs at least ONE person who has a mobile device.
2. If their phone camera doesn't automatically detect and decode QR codes, ask students to
4. Cut them out and place them around your class / school.
1. Give each group a clipboard and a piece of paper so they can write down the decoded questions and their answers to them.
2. Explain to the students that the codes are hidden around the school. Each team will get ONE point for each question they correctly decode and copy down onto their sheet, and a further TWO points if they can then provide the correct answer and write this down underneath the question.
3. Away they go! The winner is the first team to return with the most correct answers in the time available. This could be within a lesson, or during a lunchbreak, or even over several days!
4. A detailed case study in how to set up a successful QR Scavenger Hunt using this tool can be found here.
Question | Answer |
| 1. Name the salt produces when hydrochloric acid reacts with magnesium hydroxide. | Magnesium chloride | 2. Name the salt produced when nitric acid reacts with sodium hydroxide. | sodium nitrate. | 3. When sulphuric acid react is with copper oxide it produces. | copper sulphate and water | 4. Write down the difference between an endothermic and exothermic reaction. | An exothermic reaction releases heat however an endothermic reaction takes in heat. | 5. Describe what happens to the temperature in an exothermic reaction. | the temperature goes up as the heat is released. | 6. What is neutralisation? | a reaction between an acid and alkali is called neutralisation. | 7. Complete the sentence Acid turns blue litmus .... | red. | 8. Complete the equation acid +alkali ---> | a salt + water. | 9. Complete the equation acid + metal carbonate ----> | a salt + water + carbon dioxide | 10. Vinay has a solution which he thinks might be acidic. Describe two tests he could do to see if it is acidic or not. | He could use universal indicator and could also react the solution with a metal and see if it fizzes. | 11. Describe how would you make an indicator for red cabbage. | Cut the cabbage into small pieces and add boiling water to it. Use the filter paper to filter the solution. | 12. List three factors that affect the rate of reaction. | Temperature, surface area and concentration. | 13. How does increasing the concentration effects the rate of reaction, explain your answer using the idea of collision theory. | the more concentrate solution is the more it reacts. this is because there are more particles in the same volume. Therefore, the particles collide more often in a certain time. | 14. What is activation energy? | Activation energy is the minimum amount of energy that is needed in order for a reaction to occur. | 15. Give One Example of an Exothermic Reaction? | combustion or reaction between an acid and magnesium.ive One Example of an Endothermic Reaction? |
